This barrel is made for the Remington Model 1100 semi-automatic shotgun and uses a fully rifled 21-inch bore tailored for slug use. The rifled design provides dedicated slug performance compared to smoothbore field barrels.
The cantilever scope base is installed on the barrel and extends rearward over the receiver. This configuration eliminates iron sights and provides a direct mounting surface for a scope on the barrel assembly.
The chamber is cut for 2-3/4 inch 12 gauge shells. The muzzle is unthreaded with no removable choke, consistent with its dedicated slug-barrel configuration.
Construction is steel with a polished blue/black finish. The assembly includes the typical 1100 barrel ring for the magazine tube, ensuring direct compatibility with the Model 1100 platform.
